JAR oR-BoTTLEoL-osuee.

SPECIFICATION forming part of Letters Patent No. 691,38 2, dated January 21, 1902..

To @ZZ whom, it may concern:

Beit known that I, HENRY A. HUGHES, Jr. ,a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certai n Improvements in Jar or Bottle Closures, of

which the following is a specification.

My invention relates to certain improvements in that class of closures for jars or bottles which are adapted to hermetieally seal 1o the contents of such jars or bottles.

The improved closure forming the subject of my invention is preferably combined with an ordinary cap, topfor stopper, thoughA for certain purposes it may be used alone.-

The compound of which my improved closure is made is described'and claimed in a companion application, iled of even date herewith. Thiscompound possessestheproperty of swelling and becoming resilient Aor 2o rubber-like in the presence of moisture,.and

this quality serves to eiect a sealing joint between the jar or bottle and its closure. l

My invention is fully illustrated in the accompanying drawings, in Which- Figure 1 is a sectional view of a jar and its cap, showing the ordinary method of applying a closing medium. Fig. 2 illustrates a closure of the character shown in Fig. l, coml bined with a paper lining arranged within the 3o cap. Fig. 3 illustrates my improved form of closure and the special form of paper lining employed therewith, and Fig. 4 is a sectional perspective view of the form of paper lining shown in Fig. 3.

In an application tiled of even date herewith, Serial No. 43,640, I have described and claimed a new com-position of matter which/ is insoluble in all lordinary liquids, but possesses the property of swelling and becoming aolresilient or rubber-like when exposed to the action of such liquids, and 'when in such condition it is adapted to form a sealing-joint. Such composition of matter I employ with vthe improved form of closure shown and de- 45 scribed herewith.`

In Fig. l of thedrawings herewith, 1 represents an ordinaryjar for containing Syrups, fruit-j uices, and other food products, having a cap or cover 2. Carried by this cap and 5o adapted to contact with the mouth of the jar annular groove 6.

Application {iled January 17, 1901. Serial No. 43,639. (No model.)

l isa layer 3 of the composition ot matter described and claimed in the application before referred to.

In Fig. 2, in addition to the layer-ofthe composition of matter, I employ a pressed-up disk `Fig. 4v I have shown a sectional perspective viewot` the pressed-up disk or eap'. By the u use of a disk or cap ot' this character a thick layer of the sealing compound is disposed at the joint where the cap contacts with therjar when screwed into place, and a Huid-tight joint is thereby eected. The central portion of the disk/0r cap 5 may be coated with a comparatively thin layer of sealingA co'm- 7o pound. l

The caps or Stoppers are prepared'bypouring into orcoating the same with the mixture when the latter is in a plastic or semifluid condition, and the articles thus prepared are allowed to dry. When such prepared caps, covers, or Stoppers are to be employed, they are wet prior to being set in place, or they may be Wet by the contents of the jar or bottie, when they will immediately swell, and if 8o .the caps or covers have .been screwed `down comparatively close to the mouth of the j ar such swelling will effect a fluid-tight joint between the cap or cover and the jar.

I prefer to use as a lining'for the cover the 85 special pressed-up cap or disk 5, having the (Shown in Figs 3 and 4.) These paper caps or disks are placed in the cover before the sealing mixture is poured or spread therein, and l prefer to use when 9o preparing the covers a forming device, such device to [it the cover and spread the mixture over the interior of the same evenly. The mixture is thereby caused to entirely inclose the paper cap or disks, and the edge of the mixture will be brought into contact with the side of the cap.

The use of a disk or cap of paper decreases the arnountofthe sealing mixture required and serves alsol to strengthen the closure roo when the latter is under vacuum or pressure tests. In pla'ce of the paper caps or disks I may use a fabric disk-such, for instance, as that shown and described in the patent 'of Henry Albert Hughes, No. 656,548, dated August 2l, 1900. y

Another method of employing the compound in making a closure for the purpose just described would be to coat large sheets of paper, fabric, or other suitable material with the mixture, allor the same to dry,an d when thoroughly dried out such sheets into suitable shapes to be combined with jar-covv ers and serve as a closure. When used in this manner, the compound is preferablytreated with glycerin or other similar substance for the purpose of rendering it resilient with-- out the addition or contact of moisture when insoluble, a coagulent isl added, preferably formaldehyde,and during coagulation the closures formingthesubject of this present inventionareprepared.; The mixturehaving dried, it becomes insoluble, butl may be ren'- dered resilient and rubber-like, as before described, by the addition of water. I` have `also discovered that I may use the above- 'described mixture before the coagulent is added and prepare the fabric closures by coatingl both sides of the same with the soluble it is desired to use this form of closure, I wet it in formaldehyde, and the action of the latter renders the compound insoluble, and the Water of the formaldehyde renders the said compound resilient. Y

Having thus described my invention, I claim and desire to secure by Letters P atent- As a vnew article of manufacture, aclosure for jars orbottles comprising a covering or closing membeiga shaped lining for said member, and an insoluble coating compound for the lining, said lining being provided with an annular groove whereby a thicker layer of the coating ymay be disposed adjacent to the edge of the jar or bottle than is spread over the mainsurface of the'lining, said coating possessing the property of becoming resilient in the presence of moisturey and forming a fluid-tight joint between the jar or bottle and the covering or closing member.

In testimony whereof I have signed my name to this lspecification in the presence of two subscribing Witnesses.
